A kind of detected by scent pollution of perception.Foul gas refers to that all stimulate olfactory organ to cause people not steal fast and damage life cycle
The gaseous matter in border.The species of foul gas is a lot, and so far, the sense of smell with people is that appreciable odorant has 4
Kind more than 000, in recent years, to various unusual odors, the discontented mood causing and charge event are continuously increased people.
The collection of atmospheric environment foul gas adopts vacuum glass bottle spot sampling, or by the way of vacuum tank air bag
Carry out.At present, vacuum tank sampler is mostly manual hand manipulation and is sampled, and sampling process needs sample collector to have been at
In the middle of pollution environment, rely on sample collector's osmesthesia stink to produce, determine sampling opportunity, will by the subnormal ambient of sampler
Gas sucks in gas production bag.There is following drawback in this kind of method of sampling, and 1, be exposed to foul gas ring for a long time as sample collector
In border, human body olfactory sensibility itself can decline, and the identification to stink judges to become not sensitive；2 foul gas this as having
Malicious pernicious gas, human body sucks for a long time and can cause dizziness, nausea, or even other health hazard.
A kind of sample mode of prior art is using sampling bottle sampling, is pumped into sampling bottle first with aspiration pump before sampling
Negative pressure state, is then stoppered with bottle stopper, takes pollution sources scene to, relies on the sense of smell of sampling people to judge sampling opportunity, when stink comes
When, open bottle stopper gas and lean on negative pressure to enter sampling bottle, then cover bottle stopper, complete the collection of a sample.

Gas port and gas outlet, the air inlet of the gas outlet of the first two-bit triplet magnetic valve and the first two-bit triplet magnetic valve is with air even
Connect, the air inlet of sampling air pump can be realized by solenoid valve control module to the control of two two-bit triplet magnetic valves and give vent to anger
The mouth intermediate space UNICOM with seal box respectively, thus realize the air-breathing to seal box intermediate space and air blowing.In foul gas
Concentration monitor warning system detect gas concentration exceeded after, vacuum tank sampler start gas collecting program, sampling air pump open
Dynamic pumping, two two-bit triplet magnetic valve switching gas circuits are blown or air-breathing to the intermediate space in seal box, make to produce in seal box
Raw malleation or negative pressure, make the passive exhaust of airbag or pumping complete to sample.Pass through pressure sensor real-time monitoring true in sampling process
Pressure in empty van, measure-controlling unit can manually arrange sampled pressure limit value, when monitoring that in vacuum tank, pressure reaches setting value
When control sampling air pump to quit work, connect two three-way electromagnetic valves that mouth is connected simultaneously with airbag and close gas circuits, it is to avoid gather gas and let out
Leakage, realizes automatic decision and the control of sampling process.When measure-controlling unit output air blowing signal, two two-bit triplet electromagnetism
Vavle switching gas circuit mode of communicating makes intermediate space and the sampling air pump gas outlet UNICOM of seal box, and now sampling air pump is to seal box
Air blowing makes to produce malleation in seal box, and the sampler bag in compressing seal box is thus discharge the gas in sampler bag；When measurement control
During unit processed output air blowing signal, two two-bit triplet magnetic valve switching gas circuit mode of communicating make the intermediate space of seal box and adopt
Sample air pump air inlet UNICOM, air pump of now sampling, to seal box air-breathing, makes seal box produce negative pressure, thus passive makes environment gas
In body press-in sampling airbag.Pass through pressure in pressure sensor real-time monitoring seal box, pressure reaches one during sample
After determining threshold value, automatic switchover gas circuit state realizes pumping and degassing function.When sampling will at the end of collection pressure reach setting and adopt
Close magnetic valve sealed air pocket at sampling bag gas nozzle after sample negative pressure value, then stop sampling pump operating, and by remotely control
Reason module notifies sample collector's sampling to terminate.
Preferably, described sealing box material is transparent plastics material.
As shown in Fig. 2 described measure-controlling unit also includes remotely control processing module, this remotely control processing module is used
In communicating with exterior terminal, to receive the instruction that outside foul smell collection starts and terminates, control the gas circuit switching of described magnetic valve.
Sample collector can set automatic sampling configuration or Remote sampling configuration, under Remote sampling configuration, by controlling
Terminal sends sampled signal to this remotely control processing module, so that airbag is sampled；After the completion of sampling, system is automatically stopped
Sample, and sampling ending message is sent by remotely control processing module and inform that sampling terminates to sample collector's control terminal.
As shown in Fig. 2 measure-controlling unit includes described monitoring, alarming signal processing module, solenoid valve control module and adopts
Sample pump control module, described solenoid valve control module is electrically connected with described two three-way electromagnetic valves and two-bit triplet magnetic valve to control
Air circuit breaker or switching, described sampling pump control module is used for controlling the on/off of described sampling air pump.
Preferably, measure-controlling unit can also include remotely control processing module, remotely control processing module be used for
PCT communicates, and to receive the instruction that outside foul smell gathers beginning and end, controls the switch of described magnetic valve or cuts
Change.
Preferably, measure-controlling unit includes a pressure measuring module, this pressure measuring module and described pressure sensor
It is electrically connected with, in order to receive and to process the measurement data of described pressure sensor.
Preferably, measure-controlling unit includes operating Display processing module, is connected with other modules of measure-controlling unit,
To arrange Instrument working parameter and to show other module status or process other module corresponding functions.Corresponding have one in outside
The host service function screen 3 that can show and operate.
In the present embodiment, each functional module of measure-controlling unit can all be integrated in an on-chip system.
As shown in figure 3, being the typical workflow diagram of this sampling apparatus.
First operationally, instrument is started shooting, then instrument can be set and carry out airbag cleaning, then pass through monitoring, alarming
Signal processing module to density real-time monitoring alarming signal transacting, monitors whether concentration exceedes given threshold, continue if not into
Row monitoring, if exceeded, automatically control magnetic valve and sampling air pump work by measure-controlling unit, carries out foul smell sampling.
When sample completes, close magnetic valve sealed air pocket, note remote notification sampling engineer, terminate sampling.
Another mode of operation is to send startup sampled signal by control terminal and start to remotely control processing module
Carry out sample collection, the sampling of system automatic decision completes and terminates to sample.
By the above, describe a kind of indirect type intelligent automation foul gas sample devices, be used for realizing stench
The automatic identification sampling of gas scene, solves conventional method and relies on Artificial Olfactory to distinguish odor concentration, implement what hand sampling brought
Olfactory fatigue, thus causing olfactory sensibility to decline, leads to miss the problems such as sample the best opportunity, it also avoid the people that samples simultaneously
Have been at potential health of human body in the middle of toxic and harmful environment dangerous.
